Out of curiosity, what is your purpose? Do the crossings stay down long enough to cause backups sufficiently large that you alter your schedule to avoid them?

Probably yes (I'm guessing as I'm not the OP).

There's a level crossing a few miles from me that has automated barriers. The tricky bit is the crossing is right next to a station and there will be various rules in force:-

* barriers must be down at least X seconds before a train is due to go through

* barriers must be down even if the train is coming in to the station to stop (before it gets to the crossing) - the barriers must be down in case it overshoots

* etc

Whilst the barriers can go up as soon as a train has passed there may be another one along shortly enough that it's not worth opening the barriers only to close them a few seconds later.

Combine those with a timetable that puts 10+ trains an hour each direction and the barriers will probably be down for longer than they are up in peak times. I've seen them down for 10+ minutes at a time.

Here's the google streetview that just happens to have a train that has already passed and stopped at the station: https://goo.gl/maps/jhzApjZHUAJ4FcSt6

As a pedestrian (or a cyclist without lots of luggage) it's often faster to use the footbridge to cross rather than waiting for the train(s) to pass and the barriers to rise.

Wow. There's a similar intersection near me in the bay area, and it always struck me as an incredibly poor design. I'm sort of surprised to see that there's another such intersection in the world. Fortunately (?), I don't think CalTrain runs any more than every 15 minutes, so the gates are rarely down for more than a couple minutes at a time.

Originally it was curiosity, however of has moved on from that.

I work in the traffic industry.

If we can slow people down before they reach the queue, then we can reduce the impact of them joining the queue (co2 etc....).

Thanks for the link. There goes my evening ...

And my last 4 years :)
